Hello Jonathan,First of all I’m very envious of you tnikag pictures of beaches and mountains in Donegal and calling it work! I’ll email you with some contacts shortly, but some of my own favourites are the Horn Head/Dunfanaghy area; Machaire Rabhartaigh beach near Gort an Choirce; Carrickfinn beach (right beside Donegal Airport) and An Tre1 Gheal (Silver Strand) near Gleann Cholmcille in South Donegal.Gaoth Dobhair also has some lovely beaches.As regards mountains, an tEargal (Errigal) and (Mucais) Muckish are pretty iconic.I’m sure North Donegal/Inishowen has its own gems but I’m just not as familiar with that part of the county.Sle1n go ff3ill,Cathal
